It's the final week of MasterChef. Three of the best amateur cooks in the country remain - by the end of the week one of them will be crowned MasterChef Champion 2009. The three remaining contestants have to cater for the British Army under some of the harsh field conditions. First they are flown to the Highlands of Scotland where they have to cook lunch, over a fire-pit and oil-drum oven, for 30 soldiers from the Black Watch. They then return to army HQ to cater a three course dinner for the regiment's top brass at Fort George.
